A Study to Determine the Impact of Solder Powder Mesh Size and Stencil Technology Advancement on Deposition Volume when Printing Solder Paste

Karl Seelig, Tim O'Neill; AIM Solder

The drive to reduced size and increased functionality is a constant in the world of electronic devices. In order to achieve these goals, the industry has responded with ever-smaller devices and the equipment capable of handling these devices. The evolution of BGA packages and leadless devices is pushing existing technologies to the limit of current assembly techniques and materials. (...)

The goal of this study is to determine the impact on solder volume deposition between Type 3, Type 4 and Type 5 SAC305 alloy powder in combination with stainless steel laser cut, electroformed and the emerging laser cut nano-coated stencils. Leadless QFN and µBGA components will be the focus of the test utilizing optimized aperture designs.
